Fix critical bug in OpenSubtitle provider

This release fixes a critical bug in the OpenSubtitle provider causing lockdown of the application when more than two subtitles are being downloaded at the same time.

For dotnet core, download the source and run dotnet run --project ".\src\SubSync\SubSync.csproj" "\path\to\my\movies\library" from the root folder.

OpenSubtitles as default subtitle provider

Please note that the OpenSubtitles implementation was somewhat rushed and may have a bunch of bugs in it.

Download the net462-win10-x86.zip if you're on Windows 10. Requires .NET Framework 4.6.2 as it will contain the SubSync.exe

If you're running on OSX/Linux/Etc. Unfortunately you will have to build the project yourself.

First .NET Core Release

Binaries are now built as a .NET Core application.

Add a basic reporting result for when the sync is completed.
Add *.ass as one of the default subtitle extensions.
Update the console logger to use Unicode Encoding.

First github release

This release just fixes the issue with paths longer than 260 character.
